I apologize but I'm kind of confused between the workunits and the regular BOINC tasks?

G'Day Habi LK,

The regular BOINC tasks do the work of the project they belong to.

The WUProp tasks are part of this project and run basically in memory with a few minutes of CPU time here and there.

What WUProp tasks do is monitor other BOINC tasks to collect data on them, such as run time and memory requirements.
This data is collected from everyone running this project and then uploaded to this project where you can check out the information on the website and help you work out what other project applications you can run or want to run.

That is a basic run down on the project.

Each WUProp work unit runs for 6 hours no matter how fast your computer is, as it has nothing to do with processing data and uses vitrtually no CPU.

A lot of us use it to chase as many applications as we can to see how many hours we can generate per application and gain badges accordingly.

To get your first badge star you will need to run 20 applications and run them for 100 hours or more to gain the first Bronze star.
It does not take that long when you consider that a 4 core computer generates 24 hours per core per day (24*4 = 96 hours/day).
